Abstract (en)
[origin: EP0088316A2] A heat exchanger comprising a plurality of plates (5, 6) arranged adjacent to each other, whereby passages (9, 10) for two mutually heat exchanging fluids are formed between the plates. The plates comprises corrugations or ridges (7, 8), whereby the corrugations form an angle (a) with the longitudinal rim of the plate. In the first type of plates the corrugations form a first angle (α<sub>1</sub>) with said rim and in the second type of plates the corrugations form a second angle (a<sub>2</sub>) with the rim. The plates are combined in order to form two types of passages having different thermal length. The firsttype of passage (9) is obtained by combining a first plate and a second plate and the second type (10) of passage is formed by combining a first plate and a second plate, wherein one of the plates is turned 180° in its own plane. Thus, two types of passages having different thermal lengths are obtained. The two types of passages can be combined for each heat exchanging fluid in order to provide the desired thermal length for that fluid.
